Operational parameters affecting the vertical roller mill ...

Apr 01, 2017· The kN/m 2 value is the pressure of the grinding roller applied onto the grinding table. The value accounts for the projected area of the roller onto the grinding table. The projected area consists out of the mean roller diameter multiplied with the roller width on the grinding table. The working pressure in the actual grinding gap is much higher.

Vertical Roller Mill for Cement Raw Material | SINOMALY

The rotating speed of the grinding table determines the output speed, but this needs to be adjusted as different materials have different speed requirements. Grinding speed depends largely on pressure, quantity, and size of the roller, as well as table diameter, rotation speed, material thickness, and more.
